It will nevertheless be understood that no limitation of the scope of the invention is thereby intended. Any alterations and further modifications of the inventive features illustrated herein, and any additional applications of the principles of the invention as illustrated herein, which would occur to one skilled in the relevant art and having possession of this disclosure, are to be considered within the scope of the invention.

Reference throughout this specification to an “embodiment,” an “example” or similar language means that a particular feature, structure, characteristic, or combinations thereof described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, appearances of the phrases an “embodiment,” an “example,” and similar language throughout this specification may, but do not necessarily, all refer to the same embodiment, to different embodiments, or to one or more of the figures. Additionally, reference to the wording “embodiment,” “example” or the like, for two or more features, elements, etc. does not mean that the features are necessarily related, dissimilar, the same, etc.

Each statement of an embodiment, or example, is to be considered independent of any other statement of an embodiment despite any use of similar or identical language characterizing each embodiment. Therefore, where one embodiment is identified as “another embodiment,” the identified embodiment is independent of any other embodiments characterized by the language “another embodiment.” The features, functions, and the like described herein are considered to be able to be combined in whole or in part one with another as the claims and/or art may direct, either directly or indirectly, implicitly or explicitly.

As used herein, “comprising,” “including,” “containing,” “is,” “are,” “characterized by,” and grammatical equivalents thereof are inclusive or open-ended terms that do not exclude additional unrecited elements or method steps. “Comprising” is to be interpreted as including the more restrictive terms “consisting of” and “consisting essentially of.”

A general overview of function:

FIG. 4 shows the main sections as being the hydraulic cylinder, the push button valve, and the sealed air and oil external container. Oil will generally flow from the high-pressure side to the low-pressure side. The direction of the flow can be changed by the amount of weight the user puts on the hiking stick. By changing the force that is applied to the top of the hiking stick when it is upright, the pressure will go up or down which will determine the direction of the flow of the oil when the valve is open.

Description of How the Invention Operates/Functions:

When the user puts their body weight on the top of the hiking stick 3 when it is upright, it causes the second stage 20 of the hiking stick to transfer the force thru the metal tube 9 to push up against the mineral oil 11 inside the hydraulic cylinder 5, therefore, causing an increase of pressure. When the push button valve button 1 is pressed the mineral oil 11 flows thru the valve 19 and metal tube 12 to the lower pressure side container 16 outside of the hiking stick. By pushing more mineral oil 11 into the sealed exterior container 16 it causes the air 15 inside of the container 16 to be compressed. Once the user releases pressure on the push button valve button 1 the mineral oil 11 can no longer flow and prevents the mineral oil 11 to flow back into the hydraulic cylinder 5 which cause the stick to expand.

When the user desires to change the height of the hiking stick they push the button valve 1 without putting their body weight on the top of the hiking stick 3. That causes the pressure of the mineral oil in the exterior container 11 to rush thru the metal tube 12 and into the internal hydraulic cylinder 5. The force of the mineral oil 11 being exerted on the piston head 6 will cause the piston to expand and move downward. The force of the piston will be transferred thru the metal rod 9, then to the metal second stage adaptor 21, then to the hiking stick stage 2 screw adaptor 17, then to the hiking stick stage 2 plastic adaptor and then onto the stage 2 hiking stick tube 20. When the user has reached the desired height they release the pressure on the push button valve 1 and the hiking stick will once again lock in its position because the valve 19 will not allow the mineral oil 11 to flow into the external container 16 when pressure is put on the bottom of the hydraulic cylinder 9. Because of the difficulty in compressing mineral oil 11 the hiking stick will remain at that height even if you put pressure on the top part when the valve is closed.

BRIEF DESCRIPTION OF INVENTION

Adding the ability to change the height of a hiking stick with a simple push of a button.

Regular adjustable hiking sticks require the user to reach down to the bottom of each hiking sticks to adjust the height every time they are going up hill or down hill. When hiking at high elevations where oxygen and temperature levels are low, executing the most routine task become challenging. Advantageously, by using the illustrated/described hiking stick, a user may, by using their body weight to store energy in forms that include but is not limited to electricity, spring tension, mineral oil pressure or air pressure, the user can then access the energy to adjust the height of the hiking sticks with a simple push of a button.

Regular hiking sticks require the user adjust each hiking stick by more complex hand maneuvers. Currently, the user has to unscrew or unlatch each level of each hiking stick to achieve the desired height. When the user adjusts the height of the hiking stick they change the positioning of the hiking stick. Once the hiking stick is in the upright position ready for use it is often at the incorrect height and the user readjusts the hiking sticks.

Users of this invention include but are not limited to, those who spend time in the outdoors and hike in uneven terrain.

The new hiking stick will allow the user to change the height of the hiking stick with a simple push of a button. That saves the user precious time and energy when hiking at high elevations where temperature and oxygen levels tend to be low. Those conditions make it much more difficult to continue hiking due to quick exhaustion.
